It really depends on your personal preference. I don’t like having 3+ coats of glitter (because it’s evil to remove that way!) so I tend to always match them up with other polishes as a base. Or I’ll just use them over white or a black polish (depending on the glitter) to make it stand out more.

I seriously have very little room on my shelves at this point for new polishes, I keep having to go through with a critical eye! I just gave a good friend of mine over 40 polishes and it barely looks like I got rid of any lol!
